This article will explain in detail how to set default values for a date input field (such as date selector) in a PHP web page. We will explore how to ensure that when the page first loads, the field displays the date of today, and after the user submits the form, the date selected by the user is correctly captured and displayed. The core method is to use PHP conditional assignment statements to check and use the data submitted by the user first, and if none, it will fall back to the current date.
